Schwartz Bay Leaves Box 3g contains one ingredient: dried bay leaves. While bay leaves do not contain the most common food allergens, they belong to the Lauraceae plant family, which also includes cinnamon, sassafras, and avocado. Some individuals may be sensitive to bay leaves or components they contain, such as eugenol and linalool, which can cause allergic contact dermatitis in some cases. As with any product, if you have a known allergy or sensitivity, it is best to check the physical product packaging for the most current information and to consult a doctor if you have any concerns.
